toast: 기본형 Toast --> 하단 toast

toast2: 레이아웃 적용한 Toast --> 중단 COLORTOAST

추가로 toast 누를때마다 숫자 증가해서 보여주게 설정

public class MainActivity extends AppCompatActivity {

    public int number = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        Button button = (Button) findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Toast toast = Toast.makeText(getApplicationContext(), "Toast test",Toast.LENGTH_LONG);


                toast.setGravity(Gravity.TOP | Gravity.LEFT, 200,500);

                toast.setText("tttt");

                toast.show();



                toast.setText("Toast" + number);
                number++;


            }
        });

        Button button2 = (Button) findViewById(R.id.button2);

        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                LayoutInflater inflater = getLayoutInflater();

                View layout = inflater.inflate(R.layout.toastborder, (ViewGroup)findViewById(R.id.toast_layout_root));
                TextView text = (TextView) layout.findViewById(R.id.text);
                text.setText("shape Toast");

                Toast toast = new Toast(getApplicationContext());

                toast.setGravity(Gravity.CENTER, 0,-200);
                toast.setDuration(Toast.LENGTH_SHORT);
                toast.setView(layout);
                toast.show();



            }
        });


    }

스마트폰의 키 (화면하단 3개 버튼, 좌우, 전원 ...) 처리

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(keyCode == KeyEvent.KEYCODE_BACK){
        Toast.makeText(this, "BACK button",Toast.LENGTH_LONG).show();


    }
    return true;
    //return super.onKeyDown(keyCode, event);
}

키 리스트

a - z-> 29 - 54

"0" - "9"-> 7 - 16

BACK BUTTON - 4, MENU BUTTON - 82

UP-19, DOWN-20, LEFT-21, RIGHT-22

SELECT (MIDDLE) BUTTON - 23

SPACE - 62, SHIFT - 59, ENTER - 66, BACKSPACE - 67

android:state_pressed="true" // 눌렸을 때 반응

Drawable에 아래 코드 입력

<item

    android:state_pressed="true"
    android:drawable="@drawable/img1"
    />
<item
    android:drawable="@drawable/img2"
    />

ScrollView 태그 사용하면 내부 뷰의 사이즈가 넘칠 경우 스크롤이 가능하다.

ScrollView --> LinearLayout --> View 순으로 위계 정해지는듯.

귀찮아서 스샷은 패스.

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">
            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:textSize="500dp"
                android:text="이건긴글입니다매우긴글\n이건긴글입니다매우긴글\n이건긴글입니다매우긴글\n이건긴글입니다매우긴글\n이건긴글입니다매우긴글\n이건긴글입니다매우긴글\n이건긴글입니다매우긴글\n이건긴글입니다매우긴글\n"
                />
        </LinearLayout>
    </ScrollView>
</TableRow>

layer-list: shape를 중첩시켜주는 태그

shape: 간단한 스케치가 가능한 layout 설정

gradient: shape 내 gradient 색상 지정
